Python’s new template strings, or t-strings, give you a much more powerful way to format data than the old-fashioned f-strings.

Luckily, Excel offers handy formulas that allow you to convert text into upper case, lower case, title case, and even sentence case with minimal effort.

You use the "toUpperCase" function to convert a string value to all uppercase letters. You use this function when you want to display standardized data on the pages.
